Counterfactual AI Test: OpenAI's Math Proofs Hit Historic Levels

Afinetheorem · x · 2026-08-02

The author conducted a "counterfactual history" experiment exploiting LLM training cutoffs. After feeding AIs OpenAI's latest math proofs, the models assumed it was an April Fools' joke.

When asked what the reaction would be if a small human team dropped this paper, the AIs agreed they would be considered the greatest mathematicians ever. This highlights that current AI math capabilities are significantly ahead of schedule.
